I have a toshiba 65h81 that the convergence messed up on. I tried using the Touchfocus but got "touchfocus error" We went into the service menu and can't get that red to go any further down. It's only on the bottom left and top right. Took off the screen and it doesn't appear there is any issues with the red gun as we can see it move up and down, etc...
Pretty sure it's the IC chipset based on what most people have said but not exactly sure how easy/difficult of a job it is. From other posts, it looks like chips are between $7-$45.
I can get it fixed for $250...Should I have it fixed at all. Is $250 too much to fix it? If it's easy, how do I do it and does it require any sodering? Is there any other things I should check before going forward?
Also, how many chips would I need, where can I buy them and how difficult is it?
Guys, I 've replaced my STK's and and it was a 2 and a half hour challenge job for me, in the hope I solve the dreaded red light blinking issue. I have soldered both STK's nice and neat and everything looks in order. One of the problems you might face, is your soldering gun. There are 4 heavy duty pins that keeps each STK in place, and you need a powerful gun to take care of those. The rest of the pins are very small, and you need a different setup for your soldering gun. You also need a suction pen to be able to to take all those pins out.
But it's not a heavy headache, it's just a light one:)
Also the thing is to remember each wire assembly you disconnect and put it back. It takes patience, and you don't wanna destroy them :( For some , that by itself could be a challenge. The Board containing the two STK's is connected to the power board with three neat assemblies....you pry those up from the top suction, and away from the power board.
BUT, as I recall, most of the challenge has to clear that board loose.
I hope this helps.

OK, the problem is one of the STK392-110 convergence amps has died. It is rare that both die at the same time, so either vertical or horizontal will go out, but not both. Also look for an open fusable resistor near said IC.

You need to get to the service menu--it's been 4 years so go to AVSforum.com to turn off the different guns and get the better pattern.
At your risk:
To get into Service mode:
1. Turn your TV on.
2. For X81 or earlier series: Press MUTE on your remote and release.
2. For H80/H81/HX81 series: Press MUTE on your remote and release two times ("Mute" on-screen)
3. Press down MUTE on your remote again and hold. While holding, press the MENU button on your TV set's front panel. 4. Release both buttons.
5. An "S" should appear on your screen. Press MENU again on your TV.
6. Now you're in service mode. Channel Up/Dn - Scrolls through Parameters and Volume Up/Dn - Changes Parameter Value
To get into convergence mode:
Get into Service mode, then
Hit '7' to bring up the convergence grid.
Buttons 100, 0, and ENT control which gun you want to turn off (if you want to align the red to the green without seeing the blue gun and other variations).
2=up, 8=down, 4=left, 6=right, 3=change gun to converge, 5=converge that point.
To exit convergence mode you press 7 once and your screen should look like it's imploding then return to normal and then you press 7 to get back into regular service mode.
I have more info found on the board.
Good Day, klynn69;
Even though you did not ask a question, I assume you want to know what's wrong. It sounds like the TV has experienced a Convergence Circuit Failure. If you are really handy replace Conv output Amp IC's AND make sure all pico fuses are ok, all jumpers have secure connections OR call for service to An Authorized Service Center and have them come out and give an estimate B4 repair. AVG cost $550.00. Good Luck, big IRISH.
Somewhere along the line you may have missed a cable connection. Recheck to be sure that all of the wires are reconnected. Also, check the +5V line. In the area of the convergence Ics there should be a number of pico fuses. One of those may have opened up.
Keep us posted.
Does the blue and red crosses move at all ... eather vertically or horizontally. if they move at all then it may not be the chips.. could be a resistor. if the crosses dont move then it probally the ic. these chips run about 7 to 45 dollars apeace depending on type. at our shop we charge around 125 to put in.
DA, convergence circuit has failed, the IC`s and possibly a couple of support resistors need to be replaced, your right about it being a good set, 6 years is about average for convergence IC`s, call your local shops for a few estimates and get it fixed, it will run for a lot longer than 6 years, hope this is the advice your looking for, e-mail me if you have more questions, BMW Rider
